'OHARLES T. VVESTLAKE, OF GRANITE, ILLINOIS, ASSIGNOR TO COMMON- TRANSOMFOR CAR-TRUCKS.

SPECIFICATION forming part of Letters Patent No. 776,281, dated November29, 1904. Application filed January 19, 1903. Renewed May 12, 1904:.Serial No. 207,638. (NoJnodeL) To all whom it may concern.-

Be it known that I, CHARLES T. WESTLAKE, a citizen of the United States,residing at Granite, in the county of Madison and State of Illi: nois,have invented certain new and useful Improvements in Transoms forOar-Trucks, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to transoms for the trucks of railway-cars, and hasfor its object the production of a transom in which the side frames ofthe transom are firmly held united to each other at their ends both attop and bottom, so that the stress of the car and load carried will beequally divided between the side frames, which are sustained by thecolumn-bolts that unite them to the arch-bars of the truck-frame.

A further object of my invention is to provide means to prevent thedisplacement of the bolster in the transom both in vertical andlongitudinaldirections, so that the bolster will be maintained seatedupon its springs without liability of their displacement.

A further object of the invention is to provide spring-seats securelyheld in place by the column-bolts, so that they serve in addition totheir function as seats as ties by which the side frames of the transomare securely united to each other.

The invention consists in features of nov-- eltyhereinafter fullydescribed, and pointed out in the claims.

Figure I is a view, partly in plan and partly in horizontal section, ofmy transom. Fig. II is a view, partly in side elevation and partly inVertical section, of my transom. Fig. III is an end view of the transomshown positioned between the arch-bars of a truck-frame. Fig. IV is aperspective inside view of one end of one of the transom side frames.Fig. V is a perspective view of one of the spring-seats. Fig. VI is aperspective View of one of the top ties that unite the side frames.Figs. VII and VIII are perspective views showing modifications of theside frames and spring-seats.

1 designates the upper arch-bar of a truckframe. 2 the lowerarch-bar,and 3 the tiearch bars of the truck-frame. At the lower{ -edge of eachside frame 7 at each end is a re-- cess 10, that extends inwardly fromthe end of the frame and terminates at a shoulder 11.

12 designates lugs projecting inwardlyfrom the inside faces of the sideframes 7 lower edges. (See Figs. II and VI.)

13 designates spring-seats the inner endsof which are positioned betweenthe inside faces of the side frames 7 and rest upon the lugs 12 fortheir support. The outer ends of the spring-seats are widened to formarms 14, which are arranged in the recesses 10 at the lower edges of theside frames to extend beneath the lower flanges 8 of said frames and areprovided with bolt-holes 15, which receive the column-bolts I. By thisconstruction the spring-seats serve to form ties between the side frames7, so that they are firmly bound together at their lower edges throughthe medium of the seats and the column-bolts, while the inner ends ofthe springseats being interposed between the inner faces of the sideframes resist independent movement of the side framesat their loweredges. Each of the spring-seats 13 is provided at its outer end on theunder side with ribs 16, between which the lower truck-frame arch-barsat their I 2 are seated and held from lateral movement.

17 designates the top ties which are seated on the transom side frames 7at their ends and are provided with bolt-holes 18, that receive thecolumn-bolts 4:. These top ties through their connections to the sideframes by the column-bolts serve to firmly bind the side framestogether, so that the entire set of column-bolts will resist strain as aunit as a result of the presence of said ties and the springseats 13,located beneath them and also connected to the side frames, asexplained. The ties 17 extend over the ends of the bolster 5, as seen inFig. II, and by so doing serve as guards to prevent the verticaldisplacement of the bolster in the event of undue upward movement duringservice when the car equipped with the transom is in motion. The bolsterbeing confined by said ties from undue movement is always maintained onthe bolster-springs, and the springs are therefore prevented fromdisplacement by slipping from the spring-seat, as they are liable to inconstructions wherein the vertical movement of the bolster is unlimited.

19 designates limitation-stops projecting from the inside faces of theside frames 7 near their ends and by which the longitudinal play of thebolster is limited within the transom to prevent longitudinaldisplacement.

20 designates brake-hanger lugs carried by the transom sideframes 7 toreceive the connectionof hangers, by which the brake-rods of the car aresupported.

In Figs.VIl and VIII, I have shown a modification of the spring-seat. 7a in this modification designates one of the side frames,which isprovided with a slot 12, located in a position corresponding to the lugs12 of the side frames 7. 13 is a spring-seat which is provided at itsinner ends with outwardly -extending arms 13, which are adapted to passthrough said slots 12 for the support of the spring-seat in lieu of itssupport by the lugs 12.

The tie-plates 17 are each furnished with downwardly-extending flanges17 at their side edges. These flanges project beyond the top edges ofthe side frames 7, so as to em brace their flanges 8, and thereby serveto hold the side frames from twisting action under strain with respectto each other and prevent the transom from becoming distorted understrain.

I claimas my invention 1. The combination with arch-bars and atruck-transom, of guards extending across the top of said transom partlybeneath the top arch-bars and projecting inwardly from said toparch-bars to confine the ends of a bolster of a length approximately thewidth of space between said top arch-bars, whereby said bolster may bereadily positioned within said transom previous to the insertion of saidguards.

2. In a truck-transom, the combination of a pair of side members toinclose a bolster, and guards detachably mounted upon said side membersto limit the vertical movement of said bolster, substantially as setforth.

3. In a truck-transom, the combination of a pair of side members inwhich a bolster is inclosed, ties connecting the upper edges of saidside members and projecting over the ends of said bolster, and stopsprojecting from the inner faces of said side members to limit thelongitudinal movement of said bolster, substantially as set forth.

4. In a truck-transom, the combination of a pair of side members, meansfor uniting the lower edges of said members, ties uniting the upperedges of said members, and flanges projecting downwardly from said tiesto embrace said side members, substantially as set forth.

' 5. In a truck-transom, the combination of side members, spring-seatslocated at the lower edges of said side members, ties surmounting saidside members and forming independent and detachable guards, andcolumn-bolts passing through said side members, spring-seats and ties,substantially as set forth.
